my brother have scored 268 marks in neet ug so does he eligible for a bams seat ? We are from Karnataka and looking for govt seats

Nope at these mark there is no chance to get a seat in bams or bdms for get a seat in govt medical college your brother have to secured at least 450 marks As per NEET eligibility criteria, you should have passed in Physics, Chemistry, Biology/Bio-technology and English. The candidates belonging to General Category should score a minimum of 50% marks in Class 12 or HSC examination. Candidates belonging to reserved categories should have minimum score of 40%.

Therefore this is the minimum marks required to apply for NEET and further based on your score in the exam you shall be shortlisted for the course and college.

Good Luck.
